WICHITA, Kan. (AP) -- An agreement between Kansas and a federal agency will increase the capacity of the John Redmond Reservoir by nearly 30 percent.

State officials say the agreement signed Thursday would alleviate a sediment problem at the reservoir near Emporia.

The federally-owned reservoir provides water source the cooling lake at Wolf Creek Nuclear Power Plant. It currently is 40 percent silted in.

The Wichita Eagle reports (http://bit.ly/17E1Gz7 ) the agreement between the state and the U.S. Corps of Army Engineers will raise the reservation's elevation from 1,039 feet to 1,041 feet. And it increases the number of gallons available in storage from 16 billion to 22 billion.

The second step to improving Redmond's capacity will be dredging the silt and strengthening the banks of the Neosho River to reduce the flow sediment.
